Outstanding accuracy and optimal performance on these models is achieved by a microprocessor-based PID controller which regulates user-settable temperature and humidity limits.

• Proportional integral derivative (PID) controller with LCD display
• Natural hydrocarbon refrigerant
• Temperature setpoint range: 20 to 60 °C
• Humidity range: 15 - 95% RH; humidity control: ±0.1% RH

These stability chambers are designed to provide controlled temperature or temperature and humidity testing environments. These chambers offer FDA and ICH stability testing compliance. These controlled environments are crucial for product and packaging shelf life stability testing.
